SCREEN.

SPECIFICATION forming part of Letters Patent No. 280,614, dated July 3,1883.

Application filed February .13, 1883. (No model.)

To all whom, it may concern WBe it known that I, OLIN HARLEY, ofBluffton, in the county of Wells and State of Indiana, have inventedcertain new and useful Improvements in Screens; and I do hereby declarethat the following is a full, clear, and ex "a'ct description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form part of this specification, inwhich- Figure 1 is a front view, showing my improved screen appliedto'part of a window frame and tea sash. Fig. 2 is a horizontal sectionthrough the window-frame, and a top view of the screen. Fig. 3 is aperspective view of the upper end of the ratchet-wheel, its bracket, andclamping-bar. Fig. 4 is an edge view of one of the slotted platesattached to the screen-strip. Fig. 5 is a vertical section through thescreen and a window-sash, and Fig.6 is an enlarged sectional view of theupper end of the roller.

This invention relates to window-screens, and especially to improvementson the screen for which Letters Patent were granted to me 011 the 4thday of July, 1882, No. 260,67 9. The following description, when takenin con v nection with the annexed drawings, will ena ble others skilledin the art to fully under stand my invention.

A designates part of a window-frame, B the lower sash, and C G thesash-strips.

D designates a vertical bar having one edge beveled at a, and E is thescreen-roller on which the reticulated screen F is wound. The lower endof this roller is pivoted to a metal bracket, G, which is rigidlysecured to the lower end of the bar D, and perforated to receive acentrally on-the bottom of a ratchet-wheel, H,

which wheel is further secured to the roller by means of nails orscrews. The ratchet'wheel H is cast with a circular hub, d, on itsbottom side, which is received in a circular hole made through abracket, G, that is rigidly secured to the upper end of the bar D, andon top of the said wheel H a handle, H, is cast, by means of which theratchet-wheel and its roller can be turned for winding up or unwindingthe screen F.

a I designates a pawl which is pivoted on top of the bracket G, andadapted to engage with the teeth of ratchet-wheel H for preventing thescreen F from unwinding when it is drawn taut across a window-sash.

J designates a verticallyslotted lip which is formed on the outer edgeof the bracket G, and adapted to engage with a screw, 1), fixed in thesash-strip, and to serve, in connection with the bottom screw, 1), asthe means for securing the bar D firmly in place.

J designates a clamping-strip which is pivoted to the bracket andprovided with a knob handle. I pressing the screen F closely against theacute edge of the bar D, so that the screen will be close against thewindow-sash and exclude winged insects from the room when the window isup. At the lower end of this pivoted strip J is a notch, e, which allowsthe strip to clear the head of the screw I).

K designates a vertical strip, in the inner edge of which a kerf is madediagonally, as indicated at f, and in this kerf the left-hand edge ofthe screen F is secured. By means of this attachment of the screen tothe strip K, in combination with the beveled edge of bar D, and thepivoted clamping-strip J, the screen (or netting) is held flatly andclosely in contact with the window-sash.

L L are vertically-slotted plates, which are rigidly secured to the edgeof the strip K, and adapted to receive through them the heads of screwsf f, which are fixed into the left-hand window-strip C. By this simplemeans the strip K can be quickly and firmly secured to the window-stripG and detached from it at pleasure. I

N designates a narrow wooden strip secured 011 the upper rail of thelower sash, and

having a thin flexible strip, 9, of rubber or other suitable material,inserted into one edge. Thisstrip is used to prevent winged insects fromgetting between the two sashes when the lower sash is raised. It is usedon the top of the lower sash when there are sashlocks, and on the bottomof the upper sash when there is a sashlock on the inside sash.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combinatiomin a window-screen of This pivoted strip is designedfor I the character described, of the slotted plates L L on the strip K,the slotted lip J, formed on the bracket G, the screw-fastening b, andthe clamping-strip J, having a notch in its lower end, all constructedand adapted to operate substantially in the manner and for the purposesdescribed.

2. The combination, with a window-screen roller, of beveled bar 1) andits brackets, clamp J", strip K, slotted plates L L, slotted lip J,formed on bracket G, ratehetavheel H, and

pawl I, all constructed and arranged to operate substantially and forthe purposes set forth.

In testimony that I claim the foregoing as I 5 my own I afiix mysignature in presence of two witnesses.
